摘要： A keyboard has two segments connected to each other at their rear ends by a connector. The two segments can be pivoted about the connector through 90.degree. in the plane of a support surface for the keyboard. In one embodiment, each keyboard segment may be disposed at a maximum angle of 45.degree. to its support surface in a plane perpendicular to its support surface. Thus, the two segments may be tilted 90.degree. with respect to each other. The two segments may be separated and supported individually through three pivotally mounted supports on its bottom surface. Two of the supports are disposed adjacent the rear corners and pivot on the same axis while the third support is disposed adjacent a lower inner corner of the segment and pivots on an axis perpendicular to the pivot axis of the other two supports. Each of the supports has two legs of different lengths to permit various tilting configurations of each segment with one of the legs having an adjustable length in one embodiment.

摘要翻译： 键盘具有两个在其后端通过连接器彼此连接的部分。 两个部分可以在键盘的支撑表面的平面内围绕连接器枢转90°。 在一个实施例中，每个键盘段可以在垂直于其支撑表面的平面中以与其支撑表面成45度的最大角度布置。 因此，两个部分可以相对于彼此倾斜90度。 两个部分可以通过其底部表面上的三个枢转安装的支撑件分开并分别支撑。 两个支撑件邻近后角设置并且在相同的轴线上枢转，而第三支撑件邻近该段的下内角设置并且在垂直于另外两个支撑件的枢转轴线的轴线上枢转。 每个支撑件具有不同长度的两个腿，以允许每个段的各种倾斜构造，其中一个腿在一个实施例中具有可调整的长度。

摘要： A combined mouse and trackball having its control ball (15) extend past cover 1. Cover 1 has neck hinges (5) so that it pivots in relations to opposing cover (17). A cable (33) at the front communicates with the computer receiving the control signals from the ball. A switch (43) reverses the significance of front-to-back signals from the ball depending on whether an actuator (45) integral with cover 1 engages the switch. In the closed position of cover 1 the bottom of the devise is flat and the ball is upward for use as a trackball. In the open position of cover 1 the device is formed into a mouse with front and rear surfaces (67, 69) to support the ball for frictional movement on a table (71). Latch surfaces ((25, 57 and 25, 65) hold the covers in the two positions until they are manually released.
